Not really. The only new KH for water is Vohu Manah.
Everything else is the same. Just that you don't need Asherah anymore with Shiva AW and tbh I wouldn't MTix Asherah unless you want to improve water now. Otherwise use it for a different element.
I forgot to mention that Water QB isn't good for burst builds. Instead you should use Ryu-Oh or Cthulhu with Vohu Manah.
She is only good with Morgan. Otherwise don't use her for burst build unless you have cleanse.
And no, it's light who will change a lot in the future.
Burst+DMG Build: Micha AW, Lugh, Iris and Trish.
Ofc there are different kinds of Burst builds for light but that one above is just ridiciulous.
